A 20-story tall, 1.3 million-pound Atlas V rocket will blast off from Florida this weekend, and Bay Staters waking up very early might able to see it if the clouds in the sky don’t cover it.
Teams with United Launch Alliance are prepping for the Atlas V rocket launch, the fifth Amazon Leo constellation mission. Liftoff is planned at 3:53 a.m. ET Sunday, March 29, 2026, from Cape Canaveral, Florida.
Pending weather conditions and cloud cover, the Atlas V-Amazon Leo predawn launch could be visible from Florida to New England, according to ULA. That is, if their city falls on the ULA Atlas V rocket launch visibility map (see below), and if they’re awake at the time of liftoff.
The Atlas V rocket will be equipped with five solid rocket boosters to launch the next batch of Amazon Leo broadband satellites (previously referred to as Project Kuiper) into low-Earth orbit, giving a great show to those watching.
However, weather could disrupt viewing, with Massachusetts set for partly cloudy skies on Saturday night heading into a mostly sunny Sunday, the National Weather Service said.
Here’s what to know about ULA Atlas V rocket launch visibility from Massachusetts.

The United Launch Alliance Atlas V rocket will launch from Launch Complex 41 at Cape Canaveral Space Force Station in Florida in the early morning hours on Sunday, March 29. The 29-minute launch window will begin at 3:53 a.m.
The visibility map provided by ULA shows about when and where your best chances are to see the rocket as it streaks northeasterly into space.
Will Massachusetts be able to see the ULA Atlas V launch
Massachusetts, specifically Manchester-by-the-Sea and Boston, Massachusetts, falls in the semi-outer periphery of the visibility area for the ULA Atlas V rocket launch, according to ULA’s visibility map.
Estimated visibility will occur at launch +330 seconds, or about five minutes and 30 seconds, following the launch in Florida. However, viewing chances depend on weather conditions, and Massachusetts is currently set for partly cloudy skies Saturday night into early Sunday, according to the National Weather Service. This might block visibility, as clear skies are essential for best views.
